摘　　要：海口美兰国际机场场地广泛分布着玄武岩残积土,结合二期扩建飞行区、航站区及工作区的岩土工程勘察工作,分析该地区的区域地质构造,总结玄武岩残积土的地层岩性.通过静力触探试验、标准贯入试验、重型动力触探试验、平板载荷试验、反应模量试验等原位测试方法,探讨玄武岩残积土的承载力及变形特性.通过室内常规土工试验、膨胀及收缩性试验等,研究玄武岩残积土的物理力学特性.该项工作可供琼北地区岩土勘察、地基基础及地基处理工程借鉴.Basalt residual soil is widely distributed in Haikou Meilan international airport. Based on the geotechnical engineering investigation on extension project of airfield area, terminal area and appurtenant build-ing area, the regional geological structure are analyzed, the stratum lithology of basalt residual soil is summa-rized. Through the data analysis on static penetration test, standard penetration test, heavy dynamic probe test, plate loading test and reaction modulus test, the bearing capacity and deformation characteristics of basalt resid-ual soil are discussed. Through the data analysis on laboratory routine soil test, swelling test and shrinkage test, the physical and mechanical properties of basalt residual soil are researched. The word can be used as reference for geotechnical engineering investigation, foundation engineering and ground treatment of similar geological condition in northern Hainan area.
